Julie
Julie is one of Augustus Waters's two older half-sisters. She and her sister Martha live in Chicago and are both married to what Augustus describes as "very fancy lawyer dudes. Or banker dudes." Julie is married to a banker, and she and her husband have three young sons, all boys. She appears in the story during the final weeks of Augustus's life and in the immediate aftermath of his death, representing the extended family's effort to gather and support one another through a terminal illness.
Identity and Background
Julie is introduced as a half-sister significantly older than Augustus. When Hazel asks Augustus if he has siblings, he calls upstairs to his father for their ages, learning that Julie and Martha are twenty-eight. They live in Chicago, and Julie is married to a banker. She has three young sons, all boys, who are energetic and unfiltered in their comments about their uncle's condition and about Hazel. When the boys first meet Hazel, they chant "who are you who are you who are you" and one of them bluntly states, "He's dying," which the third confirms. Julie's family brings a chaotic, noisy energy to the Waters household, a stark contrast to the quiet grief of the adults.
Role During Augustus's Final Illness
During Augustus's last days, Julie and Martha are present at the Waters home, sitting with him and speaking to him in a manner that Hazel finds cloying. Julie sits on the edge of Augustus's hospital bed and coos, "Oh, Gussy Gussy, our little Gussy Gussy," a tone Hazel silently criticizes as infantilizing. When the family takes Augustus outside for fresh air, Julie kneels beside his wheelchair and tells him, "I can only hope they grow into the kind of thoughtful, intelligent young men you've become." Hazel, uncomfortable with the sentimental framing, undercuts the moment by saying, "He's not that smart," which prompts Augustus to joke that he merely exceeds expectations because most good-looking people are stupid. Julie's presence, while loving, highlights the difficulty of speaking authentically to a dying person when grief demands a performance of hope and admiration.
After Augustus's Death
Julie is present at the funeral of Augustus Waters. She speaks during the service, delivering a eulogy that follows Hazel's and precedes the closing prayer. After the funeral, Julie and Martha bring their children to the Waters home, where the boys run around the kitchen shouting and playing tag, their noise and movement providing a sorely needed distraction. Julie asks her mother if she should take the children to the park, but her mother declines. Julie's role in the aftermath is that of a family member trying to help the household return to some semblance of normalcy, even as the absence of Augustus is felt in every room.
Narrative Significance
Julie functions as a minor character who illustrates the broader social world surrounding Augustus—a world of conventional family life, professional success, and healthy children that stands in stark contrast to the cancer-stricken, medically intensive existence of the central characters. Her well-meaning but slightly off-key attempts to comfort her brother, and her children's unfiltered observations, serve to highlight the difficulty of communicating across the divide created by terminal illness. Julie's presence also reinforces the theme of family obligation and the ways in which grief is collectively managed, even when individual expressions of it feel inadequate or awkward.
